Frequently Asked Questions About CMMC Compliance
Everything you need to know about CMMC certification and requirements
What is CMMC compliance and why is it required?
CMMC (Cybersecurity Maturity Model Certification) is a Department of Defense (DoD) program for defense contractors handling Federal Contract Information (FCI) and Controlled Unclassified Information (CUI). Under CMMC 2.0, requirements phase into DoD contracts beginning in 2025; affected contractors must meet the applicable CMMC level to bid on or maintain those contracts. CMMC 2.0 is based on NIST 800-171 and is intended to protect sensitive defense information from cyber threats.
What are CMMC 2.0 Level 2 requirements?
CMMC 2.0 Level 2 requires implementation of all 110 security controls from NIST SP 800-171, covering 14 domains including Access Control, Audit & Accountability, Configuration Management, System & Communications Protection, and System & Information Integrity. Level 2 certification requires a third-party assessment by a C3PAO (Certified Third-Party Assessment Organization) and demonstrates advanced cybersecurity practices for handling CUI.
What is CUI (Controlled Unclassified Information) and how do I protect it?
CUI (Controlled Unclassified Information) is sensitive government information that requires safeguarding but isn't classified. Examples include technical data, export-controlled information, procurement data, and operational plans. Protecting CUI requires implementing access controls, encryption, audit logging, boundary protection, and data loss prevention measures across your whole environment. DataFence addresses one important vector — the browser — by warning or blocking before sensitive data leaves through browser uploads and form submissions, and by producing audit evidence for the relevant controls. It complements, rather than replaces, a full CUI safeguarding program.
How much does CMMC certification cost?
CMMC certification cost varies widely based on organization size and complexity. C3PAO assessment fees typically range from $15,000 to $150,000+ depending on scope. Additional costs include gap analysis ($5,000-$25,000), remediation implementation ($50,000-$500,000+), documentation preparation, and ongoing compliance monitoring. Tools like DataFence can reduce cost and effort by directly or partially addressing specific controls within its browser-egress scope and producing assessment-ready evidence — though a C3PAO assesses your entire environment, not any single tool.
What is a C3PAO and do I need one for CMMC certification?
A C3PAO (Certified Third-Party Assessment Organization) is an independent assessor authorized by the Cyber Accreditation Body to perform CMMC assessments. Yes, all organizations seeking CMMC Level 2 certification must undergo assessment by a C3PAO. The C3PAO conducts on-site or remote assessments, reviews evidence, interviews personnel, and validates that all 110 NIST 800-171 controls are properly implemented before issuing certification.
How long does CMMC certification take?
CMMC certification timeline typically ranges from 6-18 months depending on your current security posture. The process includes: initial gap assessment (1-2 months), remediation and implementation (3-12 months), documentation and evidence collection (1-3 months), and C3PAO assessment (1-2 months). Organizations with automated compliance tools and strong existing controls can significantly accelerate this timeline. DataFence can be deployed in hours and immediately begins generating compliance evidence.
Can software help with CMMC compliance and reduce costs?
Yes. Tools like DataFence reduce cost and effort by producing assessment-ready evidence and directly or partially addressing specific controls within their scope — for example browser-egress control of CUI (AC.L2-3.1.3, partially), audit logging (AU domain), and boundary protection (SC.L1-3.13.1). No tool confers certification: a C3PAO assesses your entire environment against all applicable controls.
What happens if I fail a CMMC assessment?
If you fail a CMMC assessment, you'll receive a detailed findings report identifying which controls were not met. You cannot bid on new DoD contracts requiring CMMC certification until you remediate the gaps and pass a reassessment. Existing contracts may be at risk of termination. Remediation typically takes 2-6 months depending on the number and severity of findings. False Claims Act violations can result in fines up to 3x the contract value if non-compliance is discovered post-certification.
